Abstract: 779,964. Stereotype plate casting apparatus. HARRIS, W., and LINOTYPE & MACHINERY Ltd. April 18, 1956 [May 24, 1955], No. 14935/55. Class 100(2) A stereotype casting machine of the type incorporating a motor-driven pump 12 for pumping molten metal from a melting pot into an arched casting chamber 15 formed between two mould members 18, 19 capable of relative movement for opening and closing of the mould, starting of the motor being effected by a manual control de- .vice consisting of a shaft 33 which on rotation by hand in one direction actuates a switch 37 in the motor circuit to produce operation of the pump is characterized by the provision of a stop device associated with the control shaft to prevent a second operation of the pump while the movable mould member 19 is in a closed position, release of the stop device being effected by the movable mould member when it is moved from its closed position to open the mould at the end of the casting operation. The shaft 33 is provided with one element 43 of a dog clutch 42, the element 43 serving as a bearing for a shaft 34 on which is mounted the other element 44 of the dog clutch. The element 44 is provided with a cam portion 59.having a slipper edge 64 for co-operation with a spring-biased plunger 62 mounted on a bracket 62 fixed to the movable mould member 19. The free end of shaft 34 is fitted with a hand lever 47 adjacent which is a bearing 48 forming part of a bracket 49 attached by a stud and nut 50 to the machine frame. A coil spring 52 is mounted between the bracket 49 and the lever 47 so as to disengage the clutch elements. The shaft 34 is biased into a position where the clutch elements on the shafts 33 and 34 are in alignment by a spring 56 connected to a stud 57 on a collar 53 attached to the shaft 34. Angular movement of the shaft 34 is limited by a stop pin 54 which projects from the bracket 49 into a segmental recess 55 in the collar 53. The pumpactuating motor is started by rotation of shaft 33 effected by pressing the lever 47 inwardly so that the clutch elements 43 and 44 are engaged and rotating the handle anti-clockwise as viewed from the right of Fig. 3. When the handle 47 is released rotation of the shaft 34 back to its normal position is prevented by reason of the plunger 62 engaging the recess 64 in the cam 59. After the pumping operation the shaft 32 returns to its original position so that until the movable mould member is opened to release the plunger 62 from the recess 64 further operation of the pump motor is prevented since the clutch elements 43 and 44 are not in angular adjustment. Specification 536,430 [Group XXVIII] is referred to in the Provisional Specification.

Abstract: 1402199 Casting composite articles; plasma arc torch electrodes VSESOJUZNY NAUCHNO - ISSLEDOVATELSKY PADEKTNOKONSTRUKTORSKY I TEKHNOLOGICHESKY INSTITUT ELEKTROSVAROCHNOGO OBORUDOVANIYA 31 March 1973 15604/72 Headings B3A and B3F A method of producing electrode units for plasma arc torches comprises forming a pool of molten metal, e.g. Cu or Ag, striking a directcurrent arc between a tungsten electrode and the pool of metal such that the electrode acts as a cathode, immersing at least a part of the electrode in the said pool and turning off the current. After solidification of the molten metal, the blank produced is machined to the required shape. The process may be carried out under a reduced pressure of inert gas, the melting of the Cu or Ag preferably being effected by the arc. In an embodiment the crucible containing the molten metal is surrounded by a solenoid the field of which causes the arc to rotate. The molten metal also rotates and forms a vortex funnel. A gradual reduction in the strength of the said field then causes the level of the molten metal at the bottom of the vortex funnel to rise so that the melt gradually surrounds the lower end of the electrode.
